To all whom it may concern:

Be it lmownthat I, RICHARD CoR ELms ELLIO'I'I, a subject of the King of Great Britain, of Glapham, in the county of London, England, haveinvented a certain new and useful Improvement in Line-Measurmg and Automatic Justifying Mechanism for Composing-Machines; and Iydo hereby declare the follow'ing'to be a full, clear, and exact description of the same, reference being had to the accompanying drawings,

This invention relates to mechanism for registerin total values in comparison with a standar and dividing the ascertained excess or deficiency into a predetermined number of parts, and is specially designed-for use in connection with key-controlled type or pattern composing machines for ascertaining the deficiency of the composed'matter and the dimensions or fractional increase in the size of the spaces or some of themjustify eachline of necessary to fill out or composition. v

I

To these ends the invention consists in the novel construction, combination and arrangement of parts as hereinafter fully described and pointed out in the appended claims.

inattention or mistakes on his The same letters indicate like parts in the several figures.

The registering mechanism includes among its principal features a plurality of individual registering devices each adapted to register adiiferent value or number of units and so connected through a differential transmission mechanism common to all that any two or more of said registerin devices may be simultaneously operated without interference, and the sum of their individual action transmitted .to the total register. v

In the preferred form of embodiment illustrated the individual registering devices are each represented by a ratchet toothed wheel or drum A, A A (three only are shown although any number desired may be employed) anda cooperating detent or escapement E; and the-difierential transmission mechanism is represented by fixed gear A movable gear A intermediate double-faced gears A, A and pinions A", each of the latter connected directly or indirectly with the ratchet-toothed wheels and carried bodily therewith.

The teeth of each ratchet wheel A, A and A differ in pitch from those of its neighbors, the pitch corresponding to different unit-values, so that each wheel will record a predetermined number of units, and alternate ratchet wheels rotate in relatively opposite directions, that is wheels A and A rotate in the same direction and A in opposition thereto.

What is herein referred to as a differential transmission mechanism is one whereby the measured motion of any individual registering device supplements that of any other of the associated individual registering devices so that when two or more of said registering devices are simultaneously operated the sum of their individual motions or measures will be transmitted to the final or total registering device or devices.

In the preferred form of embodiment of such a mechanism herein illustrated the several ratchet wheels are supported side by side and are free to revolve separately about the fixed shaft H, and each of said wheels carries upon a radially disposed axis or axes one or more (preferably three) pinions A lying transverse to and extending on opposite sides of the supporting arms or web. The pinion or pinions A pertaining to the ratchet wheel at one end of the series engages gear A fixed to shaft H, while the pinion or pinions A of the ratchet wheel at the opposite end of the series engages the gear A movable on shaft H, while the pinions of adjacent ratchet wheels -mesh with double faced gears A A, the latter turning loosely on shaft H. The arrangement is such that the motion of translation communicated from any one of the ratchet wheels to the pinion or pinions A associated therewith will effect a corresponding movement of wheel A irrespective of the position of.

said ratchet wheel in the series. Thus if the ratchet wheel next the loose wheel A is advanced, the motion of translation of its pinion A will cause the latter to revolve. about its axis by virtue of its engagement with the now stationary gear A, thereby effecting a proportional advance of the gear A. In like manner if ratchet wheel A is advanced its motion of translation in conjunction with its engagement with the now stationary gear A will effect a corresponding advance of gear A, but in a direction opposite the movement of ratchet wheel A so that if the latter is at the time stationary,

the movement thus communicated to gear A will be transmitted through the pinion A of the ratchet wheel A to gear A sa1d pinion A being free to turn upon its axis and thereby communicate the motion of gear A to gear A". If two or more of the ratchet wheels are advanced at the same time the sum of the movements of translation of these respective pinions A will be transmitted to gear A Thus, if the ratchet wheels A and A advance simultaneously and in relatively opposite directions, the

V 55 the spring, an

60 teeth on each of the wheels A, Aflahd A,

motion of translation of the pinion pertaining to ratchet wheel A will correspondingly advance gear A in the same direction with said ratchet wheel, the motion thus given 5 being transmitted through pinion A of ratchet wheel A to gear A, and at thesame timethis motion is augmented or in,- creased bythe movement of translation of pinion A derived from the motion of its 10 ratchet wheel A And ifratchet wheel A is also advanced at the same time with ratchet .wheels A A the motionof translation communicated to its pinion A will correspondingly increase .the extent of rotary motion transmitted to gear A".

The registering mechanism is under the influence of a motor, preferably provided with a spring, of which latter one end is connected to a wheel A 'in gear with pinion A and the other to a-winding drum in the usual manner, said motor tending to rotate the members thereof but actually rotating only such as are released by the respective detents E, as hereinafter explained. There is a tendency, therefore, to run down this spring and means are provided for winding the same up, as required, to maintain the desired degree of tension or pressure. To

this "endlthe windingdrum to which the spring it attached is provided with a ratchet wheel A, Fig. 1, on whose spindle is mounted an 'arm A carrying a pawl A engaging the teeth of the ratchet wheel, a suitable holding pawl beingzalso provided vfor preventing returlr motion. Coupled "with arm A is a rod A carrying a iston A working in a cylinder AP, the atter communicating with vthe air pressur chamher through the character keys of the key 40 board in such manner that each character 'key when struck will admit air under pressure to cylinder A with. a tendency to force the piston forward and cause pawl A to advanceratchet wheel A and wind up the Q spring. j I a To regulate the action of the, piston andto retract the 'latter after pressure in its cylinder isw'ithdrawn, a spring A? is inter-' posed between two collars A"'-?, A, loosely fitted to rod A, one of said collars A engaging'a shoulder onthe rod and a fixed abutment, such as theend of the cylinder A, and'the other A, held to. the rod by adjusting nuts, for varying the tension of abutment A 4. 7

In order that the total registerin" or admeasuring devices, may be advance in ac- ,cordance with .or ro ortional tothe number of unitsregistere t e pitch of the ratchet V are made'to' correspond to certain units 1 which the various ty occupy, or -some of these tEpe may be m tiples of the unit indi cat'ed' y the teeth of the ratchet wheels.

vFig. 4, tooth E will be interposed in the arranged to engage a fixed Thusin the example shown the teeth of wheel A are spacedto correspond with a measure of two units, those of wheel A three units, and those of wheel A five units, and mechanism is provided by which each of these wheels may be moved the distance of one or two teeth at will. Provision is also made whereby any one, two or all the wheels can be advanced separately or simultaneously as required Thus through the differential gear the cumulative eflect of the different registering devices when actuated separately or 7 simultaneously is imparted to the total measuring devices.

The movements of each of the several individual registering devices are determined and controlled, in the present instance, through the medium of an escape-merit device E in the form of a T-bar furnished opposite its ratchet wheel or drum 1n position to oscillate transversely of the teeth thereon. The escapements E pertaining to the first'and third ratchet wheels A and A are indicated by dotted lines in Fig. 2, while that of thesecond wheel A does not appear in said figure since it is mounted on the opposite side and obscured by the drums. The teeth E E E, are spac'edin the direc- 5 tion of movement of the escapement device E, to permit successive 'teeth to be interposed in the plane of movement of the ratchet wheel, and the two outer teeth E and E are also spaced from the intermediate tooth E", in the direction of the plane of movement of the ratchet teeth, by an amount I somewhat lesspreferably one half-the pitch of the teeth on the ratchet wheel with which they are associated.

Teeth E and E are fixed on the escapement bar, and when the latter is in its intermediate or normal position tooth E lies in the plane of movement of the ratchet teeth and through its engagement with one of the latter holds the registerin devices stationary against the pressure 0 the motor tending' to advance the same. If, now, the escapement device is moved to the right,

path of the ratchet l teeth simultaneously with the withdrawal of'tooth Ei, andthe registering device will be permitted to advance under the influence of its motor until arrested by the engagement of said tooth Ff, and upon the return of the escapemen't device to normal position tooth E will besubstitut'edv for tooth E? and the measured movement of the registering device equal to the pitch of the ratchet teeth will he com pleted. Thus the movement effectedE-by the successive presentations of these teeth" E, I E, corres onds with the units of the reglsteringdevice with which they are associated,

this unit as before explained being equal to order to permit a movement of the registering device when said tooth E is brought into engagement which is a multiple of the unit represented by toot-h E*. To this end said tooth E is mounted upon a slide movable in a slot or way 0' in the escapement bar and is provided with a retracting spring 6 tending to retain said tooth at one extreme of its movement. It is obvious therefore that when the escapement device is shifted to the left, Fig. 4, and tooth E is thereby brought into engagement with the ratchet teeth, the registering devices instead of being arrested after completing a fraction of one unit as in the case of tooth E will be permitted to advance one and a fraction units, so that upon the return of the escapement device to normal position and the reengagement of tooth E the registering devices will have completed an advance equal to two units.

By so proportioning the teeth of the ratchet wheels, when but three of these are employed, that the unit or pitch of one equals two type units, the second three type units and the third five type units, and controlling the movements of each ratchet wheel through an escapement competent to effect an advance of either one or two units, all the type unit measurements from two to twenty can be recorded.

Each escapement bar is maintained in and returned to normal or intermediate position by spring-actuated pins E working in supports E and engaging the arms E, E on opposite sides of pivot c, and beneath each arm E, E of each escapement bar is arranged one of a series of bars F, the latter operating to shift the escapement bars to the right or left and cause an advance of the associated registering devices of one or two units.

To adapt the registering mechanism to the machine of Patent No. 654,115, the escapement actuating bars F are disposed above the series of levers J (the punch levers) representing space value and controlled by the keysof the keyboard, so that one of said bars F may serve for all characters of the same type unit value, the bars F being notched or cut away opposite all the levers J save such as represent the same number of type units.

In adapting the improvements to the composing machine of Patent No. 897,358, the selective escapement actuating bars 1F may also be employed. According to this arrangement the casting of the type is governed by a series'of separate controllers or selectors each having perforations controlling valves governing mechanism for bringing into position a corresponding matrix, and a portion of said machine, sufficient to indicate the application of the present improvements thereto, is illustrated in Figs. 7 and 11, the first representing the keyboard selecting and the second the mold adjusting devices.

Each finger key 0 pivoted at O engages a longitudinally movable bar 0 the latter in turn engaging a longitudinally and laterally movable bar J to bring its shoulder O" opposite a reciprocatory driver The bar 0 in moving also engages transverse bar 0 common to all the bars O and through a lever connected therewith actuates a valve 0 to admit pressure to a motor 0 the latter connected to driver 0 The driver 0 acting upon the bar 0 imparts longitudinal motion to the escapement rod 0 that controls the delivery of the selectors 0 In the operation of the machine of Patent No. 897,358, the selectors after being assembled to represent a line of composition are delivered one at a time, and in sequence, to the matrix selecting mechanism, the latter provided with a series of movable members '1, each carrying a matrix block N whose thickness or that of its carrier corresponds directly or proportionally with the setwise dimensions of the type or space represented thereby.

The selected matrices are presented singly to the mold between a fixed abutment N on one side and a spring bufler N on the other, said buffer being coupled with moldblade N through a sizing plate N The arrangement is such that the advance of the mold blade in the direction of the fixed abutment is measured and determined by the interposed matrix, and the mold cavity is thus sized to correspond with the thickness of the matrix at the time in position.

The matrix and associated mold dimensioning device represent what may be termed the primary adjusting means, or that by which the mold is dimensioned to accord with a selected character or matrix, whose size is predetermined and not subject to variation other than by substitution. Provision is made, however, for controllably varying the measurements derived from the primary adjusting means and this is accomplished through the agency of supplemental adjusting devices normally disconnected from, but capable of being automatically coupled with, said primary means, as will presently appear.

5 plies its pre Supported in a pivoted frame N and yieldingly held elevated above the path of a bearing block N on sizing plate N5 is a longitudinally adjustable wedge N adapt ed to enter and be clamped between the rear of buffer N and bearing block N when said frame N is in its lower or depressed position.

The members T carrying blank or spac matrices are longer than those equipped with character matrices, as indicated in Fig. 11, wherein a matrix is shown in position between fixed abutment N and buffer N, the carrier for the character matrix being indicated in full lines and the extension of the blank or space matrix carrier in dotted lines .L It follows from this construction that when a character matrix is inserted from above between abutment N and buffer N and seated on the mold its carrying member T will pass arm N without displacing frame N and the gaging of the mold will be effected by the conjoint action of the fixed abutment N matrix N buffer N sizing plate N and mold blade N and whenever a blank or space matrix is inlike manner presented to the mold the extension? N of its carrying member T will overlap and engage arm or extension N of frame N thereby depressing the latter and seating its wedge N between'buffer N and bearing block N of sizing plate N so that the subsequent advance of the sizing plate and mold blade, instead of being as before measured by the matrix alone, will now be meashind the movement of the keys and levers J and unless means are provided to overcome this the speed at which the key-operator can proceed will be reduced. In the embodiment illustrated this objection. is overcome by mounting the translating and transmitting pinions A of each ratchet wheel upon a frame or support A independent of the ratchet wheel and rotatable relative thereto on shaft H within predetermined limits, instead of mounting said pinions directly upon the ratchet wheel. Thus each frame A carrying pinions A is providedwith a shoulder A", Fig. 3, in position to engage a shoulder A on the associated ratchet wheel or drum, and a spring A, one end whereof is coupled with frame A and the other with the ratchet wheel, serves to hold said shoulders AR A together, and if separated, ap-

.tsnre in a direction to cause their approach. By this means the differential gear is enabled to overtake the keys and transmit the correct amount of rotary motion to the total registering devices here.-

inafter described at whatever rate of speed the keyboard operator is working. .7

It remains to describe the total registering devices, their connection with the individual registers and differential gear,-and the automatic control of the-mold adjusting devices through said total registering dev1ces.

wheel meshes with pinion A of the units registering mechanism and is connected through a pinion 0 fast on its shaft 0' with a second gear D, hereinafter styled the ems Wheel, the latter turning freely on a stud axle or. shaft D It is desirable that means should be prodisconnected from the registering devices A gear G, hereinafter styled the units acting upon pinion A to permit said units wheel to be returned to an initial or zero po sition. In the example given thisunclutchcan be swung into or out of gear with its driving pinion while retaining its connec-.

tion with the ems wheel. A spring K ,'Fig.

1, engaging an arm is of frame K, serves for holding the units wheel in engagement with pinion A", while a motor K acting in I opposition to said spring provides a convenlent means for releaslng said units wheel from the driving pinion.'

Units wheel C is graduated and with figures representing type units and in the example given it is marked to represent the units in an em as denoted by the ems wheel, in other words, the marln'ngs on the units wheel are divided into .succes 1 sive series of twenty units each, that being the number of units in an em each of said series being divided up in increments of five units, and the latter again subdivided into increments of "one unit each. This division and subdivision is convenient in cerniarked tain classes of work where great accuracy facilitates the reckoning, as the number of 1 ems can be read on the ems wheel'at the pointer d, and the odd units beyond an em can'be read at the-point where the unit wheel passes behind the ems wheel, or at a supplemental pointer properly located.

The ems wheel D driven by the units wheel C through a pinion on shaft 0 is in ,efi'ectjaf attached disk with em I graduations. Mounted to rotate about an axis co ncident line scale and is marked on its face or on an 85 vided whereby units wheel C may be readily with that of the ems wheel D, preferably on a sleeve carried by said wheel, is a pointer D registering with the scale on said wheel and adapted to be set by the operator before composition begins, to measure or indicate the length of line, said pointer carrying a stop D adapted to engage a stud or pin C on the units wheel pinion C.

In the illustration, Fig. 1, pointer D is shown as set for a line of twenty-five ems and in starting position with stop D engaged with pin C and preventing further retrograde motion of the ems wheel so that when set back or returned at the beginning of a line said wheel will be arrested twenty five units distant from its zero position representing the opposite extremity of the line; in other words, the composition will be completed when the zero mark cl is brought into registry with stationary finger d. During composition the ems wheel is rotated in the direction of the arrow, Fig. 1, in opposition to the pressure of a restoring spring D one end whereof engages the ems wheel while the opposite end is attached to a fixed sup-.- port, such as axle D whereby power is stored for returning the ems and units wheels, at the completion of the line, when frame K is tilted to uncouple the units wheel from its driving pinion A The return motion under the influence of spring D is arrested at the beginning of the measure indicated on the ems wheel by the engagement of stop D with one of the three pins C The measure for the line need not be in ems or half ems as indicated by the divisions on the ems wheel, but may be in units of the ein the fraction being read upon the units wheel, and for this purpose the line scale indicator D and stop D are rendered adjustable relatively to the ems wheel.

An adjustment for an even number of ems is provided for by arranging the arm D so that it can move longitudinally on its support on the ems wheel and clamped in position thereon by suitable means, such as the thumb nut d, and providing said arm with one or more (preferably two) teeth d in position to interlock with the teeth of the ems wheel. By loosening the nut, arm D can be moved radially against the action of a spring (Z to withdraw teeth (1 and permit the arm to be set on any of the graduationsof the ems wheel, and when released the spring will carry the pins into engagement with the teeth of the ems wheel and the nut can then betightened.

Toprovide for a fractional setting of the ems wheel the stop D is made in'the form of a bell crank lever, pivotally connected at (i to arm D one arm of said lever being bifurcated and engaging an eccentric D surrounding the sleeve of the ems wheel between clamping nut (Z and arm D Upon releasing and turning the eccentric, stop D can be adjusted to arrest the ems wheel one or more units to one side or the other of the em mark indicated by arm D The motion of the ems wheel derived from the key controlled registering devices and representing the sum of the type units contained in the line of composition compared with the predetermined line measure, may be transmitted either directly, or, preferably, indirectly to the final registering devices. Thus, in the example illustrated, the ems wheel is furnished with a pin or projection D in position to engage and move arm I) of a toothed sector B swinging from axle D in rear of wheel D, said sector mesh ing with pinion B, of a transmission gear B. Preferably pin D is arranged to act as a pickup for sector B to which end its initial or zero position is set at a distance from that of the sector equal to a predetermined number of units or section of the line measure so that the sector and connected parts will not be displaced until the predetermined number of units shall have first been measured and registered. During the approach of pin D the sector is held against a fixed stop B by a retracting spring B 9, Fig. 1, the latter serving to return the sector and connected drum or drums to initial position upon the withdrawal of the pin incident to the resetting of the units and ems wheels at the beginning of each line of composition.

Drum-B" is provided with a plurality of circumferential cam surfaces or spirals of relatively different pitches, serially disposed according to their value, and supported to rotate in unison about a common axis. The cam surface of maximum pitch or inclination is located at one end of the series and whatever its pitch or maximum departure from the axis, the pitch of the second cam in the series will be one half the first, that of the third, one third, that of the fourth, one fourth, and so on in arithmetical progression, the number of cam surfaces employed equaling the maximum number of'justifying spaces permitted'or liable to occur in the longest line the machine is equipped to deal with. The lowest or starting points of the several cam surfaces are equi-distant from and parallel with the axis of rotation of the drum, and they extend through equal arcs around the drum; although, if desired, the wider portions of the first two or three cam surfaces may be cutaway or omitted, as indicated by the dotted lines, in Fig. 10, wherein the first cam of the series is represented, inasmuch as the area 'of justification, i. 6.,

the amount of line shortage capable of being ity of the mold adjusting devices controlled by, the drum, if applied to a single space type, would be insufficientto fill out or justify a line the measure of whose shortage,

as indicated by the revolution ofthe drum, falls within the dotted section of the cam,

ery to correspond with one of the series of cam surfaces mentioned, 7 said disks fitting the exterior of a cylindrical body 'piece, the latter provided with one or more detachable heads B, between which the series of disks are clamped and held. The drum as a whole is mounted upon a shaft B carrying pinion B for engagement through idler B with the transmission gear B,- the connection being of such character as to permit free movement of the drum longitudinally of the shaft, but to compel it to rotate in unison with said shaft. Any competent meansmay be employed to secure these results, and in the illustration the drum is fitted to slide upon its shaft and the latter has secured to it one or more rods B parallel therewith and passing through bearings in the body of the drum. The body or cylindrical center of the druin is also provided with one or more (preferably two) longitudinal opena bar B provided with shouldersB Bi, en-

I to the end that the different cam surfaces fixed point, the latter located one unitin ads Vance of the first or.one-space' cani,-surfaceT .65 when the drum is in .retracted. or ze1 o;p osiings for thepassage of retracting springs B, the latter attached at one end to the frame supporting rods B and at the other end to the head B remote thef'efrom, said -springs servingto retain the drum in and return itto its initial position or point.

starting Means are provided whereby for each justifying space composed, drums B* .will be shifted longitudinally of its shaft a uniform distance corresponding with the width-of the cam surfaces 2'. e., the thickness of the disks B Thus, in the example illustrated,

gaging opposite ends of the drum and supported upon guides to move in parallel with shaft B is. provided with rack "teeth meshing with a 'pinion'coupled with a ratchet wheel G, the latter engaged byaholding pawl and an actuating pawl G; The actuating pawl is coupled'with orcontrolled by the justifying space key'to cause an advance of-the drum eachtime said key is actuated,

may be presented in; sequence opposite a tion, so that the first movement of the drum accompanying the selection of the first justifylng space will present the first or fulli measure cam, thesecond movement will present the second or one half measure cam and so on 1n sequence, the cam surface ,corree -sponding numerically with the space being .each time presented. 3

i At the point with reference to which both I thelongitudinal and rotary movements of the drum are performed is located 'a, feeler M movable radially of the drum to contact with thatone of the cam surfaces at the time presented The position or degree of motion of' this feeler is thus measured by the cam surface of the drum andis thb quotient of the indicated line deficiency divided by the total number of justifying spaces in the line,

the line deficiency being measured by the intervals between the point of contact'of'the point of the latter, and the divisor or number of spaces by the'pitch of the cam surface movement of the drum.

The position of the brought into alinement by the longitudinal position of the selected and adjusted cam surface, corresponds with or is proportionalto the amount necessary to be added to nora I -feeler wlth the cam surface and the starting feeler -M. or the de- 'gree of displacement occasioned by the inter- 1 mal. spaces in order; to absorb the'line deficiency and thereby justify the line, hence it is only necessaryvto couple said feeler with the mold adjusting devices to-efi'ectfautomatic justification; One form of such connecting mechanism specially adapted to the machine of Patent No. 897,358 is illustrated in Fig.11. According to this arrangement a lever M pivoted at M has one end engaging 'a shoulder on rod M, the latter provided with a sliding connection with justifying wedge, while thejopposite end of said lever is, engaged by feelerM the latter guided in a casing M. A. spring N acting upon rod M tends at all times to move the wedge N longitudinally in a direction to bring its base or'widest portion opposite the interval betweenspring buffer N and bearing mold to produce the largest available space, while -a .spring"m engaging feeler'M tends to retract-and hold the latter from contact with the'drum, thus leaving the latter free to rotate and reciprocate under the influence of the"line measuring and'space counting N indicating the maximum adjustment of the:
